Matthew ★★★★★

I popped one of these red silicone o-rings onto my home brewing kettle's lid and it sealed perfectly with no leaks. The 70 durometer feels sturdy but still flexible enough to slide into the groove easily.

Violet M. ★★★★★

The 0.21” cross-section on these rings is noticeably sturdy compared to thinner ones I’ve used, and the FDA compliance gives me peace of mind for food-contact projects. They seated perfectly in my pressure canner lid without any twisting.

Chloe G. ★★★★☆

The packaging held 18 rings with no visible flash or defects, and the red color makes them easy to spot during assembly. I’ve used the same dash size from other suppliers before, but these feel slightly more pliable when seating into the groove. They’ve held up fine in a hot water application so far
